4 LM3561EVM Set-Up

To operate the LM3561EVM the following steps must be taken:

1. Download the LM3561 Graphical User Interface (GUI) from www.ti.com. The downloaded .zip folder

consists of 2 files: the LM3561.exe and the USB2ANY.dll. The .zip file must be copied and the files

extracted to a folder on a PC. Both files must reside in the same folder.

2. Ensure there is a jumper connected from VIO to VIN or from VIO to 3.3V. This is the jumper at the top

left of the board. This will connect the I2C pull-ups, the HWEN pull-up, and the STROBE button (B1) to

a logic voltage.

3. Connect a (2.7V to 5.5V) power supply across the red and black banana plugs. Red (+) and Black

(GND).

4. Connect the USB2ANY, USB Interface module with the supplied 10-pin cable to the LM3561

evaluation board.

5. Connect the USB2ANY, USB Interface module to the PC with the LM3561.exe installed.

6. Launch the LM3561.exe

5 LM3561.exe Graphical User Interface (GUI) Instructions

The GUI for the LM3561 is designed to fully demonstrate all the features of the LM3561 Flash LED Driver.

The GUI provides the interface between the PC and the Texas Instruments USB2ANY, USB Interface

Module. A picture of the interface program (LM3561.exe) is shown in Figure 6. The GUI is broken up into

different sections that correspond to the available registers within the LM3561. Operation of the GUI is

fairly basic. When any button is pushed/un-pushed or pull-down menu is selected, the appropriate I2C

command will be automatically written to the LM3561. The following section lists the register descriptions

for the LM3561.
